Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Anterior height Ha | 18 mm |
|---|---|
| Middle height Hm | 22 mm |
| Posterior height Hp | 26 mm |
| Adjacent normal posterior height (optional) | 27 mm |
→Genant grade2
- Wedge (anterior) loss：30.8 % → 25–40%: grade 2 (moderate)
- Biconcave (middle) loss：15.4 % → < 20%: grade 0 (normal)
- Crush (posterior) loss：3.7 % → < 20%: grade 0 (normal)

What are the key clinical points for Vertebral Compression Fracture Height Loss (Genant)?
Lateral thoracolumbar radiograph or sagittal CT. Each value is graded against published reference ranges. Measurement technique and positioning change the numbers — compare like with like on follow-up. Part of the YuanDoctor MSK measurement topic.
What are the limits and cautions when using Vertebral Compression Fracture Height Loss (Genant)?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Vertebral Compression Fracture Height Loss (Genant) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Vertebral Compression Fracture Height Loss (Genant) calculated in practice? Can you show a worked example?
